Mobs have difficulty pathfinding to water when they need to jump over a block

When a mob has no other option than to jump, and water is one block away, they will pause for a long moment before jumping up and getting into water. This did not occur in 1.17.

This happens with all mobs (except cats, who seem totally uninterested in water).

Expectation:
Mobs commit to jumping over that block sooner.
